3Why convert PNG to WebP?
Understanding the strengths and limitations of each format helps you decide when converting from PNG to WebP makes sense. PNG was created in 1996 as a patent-free alternative to GIF after the Unisys LZW patent controversy. It rapidly became the standard for lossless web graphics. Developed by Google and first released in 2010, WebP was designed specifically for the web. It uses predictive coding based on the VP8 video codec to achieve superior compression.

PNG (Portable Network Graphics) and WebP (Web Picture Format) serve different purposes. PNG is a raster-graphics file-format that supports lossless data compression.
